DETAILED DESCRIPTION OF THE INVENTION

Reference will now be made in detail to the preferred embodiments of thepresent invention, examples of which are illustrated in the accompanyingdrawings. Wherever possible, the same reference numbers will be usedthroughout the drawings to refer to the same or like parts.

FIG. 1 is a block diagram of a terminal 1 according to an embodiment ofthe present invention. The terminal in the present invention is any typeof terminal capable of executing an operation on the terminal via awindow. For example, the terminal can be a personal computer or laptopcomputer using the WINDOWS operational system by Microsoft Corporation.The terminal may also be a mobile terminal such as a PDA, a mobilephone, a game player, and the like.

The following description refers to the terminal being a mobileterminal, but the invention applies to the other types of terminals aswell. As shown in FIG. 1, the terminal 1 includes a communicating unit10, an external device interface unit 20, a display unit 30, a memoryunit 40 and a control unit 60. The terminal 1 also includes othervarious additional elements (e.g., a battery unit) that are not shown inthe FIG. 1.

In addition, the communicating unit 10 enables the terminal 1 to carryout Internet communications with an external environment, and enablesthe terminal user to have voice communications with another party.Further, the external device interface unit 20 allows the user toconnect an external device to the terminal 1. For example, the externaldevice interface unit 20 may be a USB (Universal Serial Bus) interfaceallowing a user to connect a USB memory to the terminal 1.

Further, when an Internet website ID and password are stored in the USBmemory, and when the USB memory is connected to the terminal 1, thecontrol unit 60 automatically recognizes the USB memory has beenconnected to the terminal 1. The control unit 60 also recognizes thatthe information stored in the USB memory is an Internet website ID andpassword, and automatically connects to the website using the ID andpassword.

In addition, the display unit 30 displays various types of informationrelating to currently executing functions. In particular, the displayunit 30 displays at least two windows under the control of the controlunit 60. The display unit 30 also displays a universal toolbar for theat least two windows. Further, the display unit 30 may include a touchscreen that the user can touch to select or input information into theterminal 1.

In addition, the memory unit 40 stores various types of software,firmware, and/or data used for operating the terminal 1. For example,the memory unit 40 may store an Internet website ID and password. Thecontrol unit 60 may then use this information to connect to the websitecorresponding to the Internet website ID.

Further, the input unit 50 allows a user to input various types ofinformation or commands into the terminal 1. Also, when the display unit30 is a touch screen, the input unit 50 can be omitted to simplify theconfiguration of the terminal 1.

In addition, the control unit 60 controls the communicating unit 10, theexternal device interface unit 20, the display unit 30, the memory unit40, and the input unit 50 to thereby control an overall operation of theterminal 1.

In the below described embodiments, it is assumed the mobile terminal isexecuting Internet browser windows. However, the present invention isalso applicable to other type of windows such as a document editorwindow (e.g., MS-WORD).

FIRST EMBODIMENT

A method of controlling windows according to a first embodiment of thepresent invention will now be explained with reference to FIGS. 2 and 3.FIG. 1 will also be referred to in this description.

As shown in FIG. 2, the method includes displaying at least two Internetbrowser windows on a screen of the display unit 30 (S21). Note that FIG.3 illustrates three windows 100A, 100B and 100C being activated anddisplayed and another window 100D being displayed as a minimized window.In FIG. 3, the three windows 100A, 100B and 100C include individualtoolbars 110A, 110B and 110C, respectively. The three windows 100A, 100Band 100C are preferably configured to interoperate with each other.

In particular, and as shown in FIG. 2, when a command is input to one ofthe display windows (S22), the input command is input to the one displaywindow (S23) and also to the other displayed windows (S24). Forinstance, when the user inputs a ‘reset’ command into the window 100A,the ‘reset’ command is also automatically applied to the windows 100Band 100C. In addition, the ‘reset’ command is preferably applied to allof the three windows simultaneously. Thus, in this example, each windowwould be reset or reloaded.

Further, it is also possible that the ‘reset’ command is applied to theminimized window 100D. The user can decide whether the command is goingto be input to minimized as well as the other displayed windows byselecting the appropriate menu options provided on the terminal 1according to the present invention.

In addition, other types of commands include a ‘search’ command, a‘log-in’ command, a ‘print’ command, etc. Thus, the user can enter aplurality of different commands into one window, and have that commandexecuted in the other displayed windows.

For example, and with reference to FIG. 3, when the user enters acertain keyword in the keyword input box 120A of the window 100A, theentered keyword is also applied to the other windows 100B and 100C.Therefore, in FIG. 3, the user can simultaneously search for aparticular keyword using the YAHOO search program in the window 100A,the GOOGLE search program in the window 100B, and the ALTAVISTA searchprogram in the window 100C

A similar concept applies to the ‘print’ and ‘reset’ commands. That is,the user can select the ‘print’ or ‘reset’ menu options shown in thetoolbar 110A of the first window 100A, and have that command alsoexecuted in the other windows 100B and 100C. Further, for the ‘print’command, the content of each window can be printed on separate pages, orthe contents of each window can be printed on one page.

The user can also set the printing characteristics by using theappropriate menu option provided on the terminal according to thepresent invention. For example, when the user selects a ‘print’ commandin one of the toolbars, a menu option may be displayed asking the userif he or she wants to print the contents of all displayed windows on asingle page or on separate pages.

SECOND EMBODIMENT

The second embodiment is similar to the first embodiment, except thatthe user designates which windows are to simultaneously receive an inputcommand. That is, the user may want to selectively apply the inputcommand to only some of the display windows instead of applying theinput command to all of the windows.

FIGS. 4 and 5 illustrate features of the second embodiment. FIG. 1 willalso be referred to in this description. As shown in FIG. 4, the controlunit 60 displays at least two windows (S41) on the display unit 30 basedon instructions input by the user. FIG. 4 illustrates the four windows100A, 100B, 100C and 100D being displayed (similar to FIG. 3). However,as shown in FIG. 5, the four windows 100A, 100B, 100C and 100D windowincludes selection boxes 130A, 130B, 130C, and 130D, respectively, thatthe user can select to designate windows that are to be operatedtogether (i.e., that a command input into one window is also input intothe other selected windows).

Therefore, as shown in FIG. 4, the user selects the windows that he orshe wants to interoperate with each other by selecting the appropriateselection boxes (S42). The following description assumes the user hasselected the selection boxes of the three windows 100A, 100B and 100D.

Then, when the user enters a command into the window 100A (S43), thecommand is applied to the window 100A (S44) and also to the windows 100Band 100D that the user has selected (S45). Therefore, the user canselectively decide which windows are to be operated together such thatthe user can enter any of the commands ‘reset’, ‘search’, ‘log-in’,‘print’, etc. into one window and have the command automaticallyexecuted in the other designated windows.

THIRD EMBODIMENT

The third embodiment of the present invention relates to the ‘log-in’command being applied to multiple windows. FIGS. 6 and 7 includefeatures related to the third embodiment. FIG. 1 will also be referredto in this description.

First, the below table includes a terminal user's ID and password foreach Internet site, and this information is stored in the memory unit 40of the terminal 1.

TABLE 1 Internet Site ID Password Yahoo chulsoo ch1234 Google chulsoo1ch1235 Altavista chulsoo2 ch1236 MSN Kimchulsoo kim1234

In addition, the IDs and passwords for the Internet sites in Table 1 maybe equal to or different from each other. As shown in FIG. 6, the threewindows 100A, 100B and 100C are activated and displayed and the window100D is displayed as being minimized (similar to the other embodiments).

Further, in this embodiment, when the user enters or inputs an ID andpassword to the window 100A (i.e., the YAHOO website), the control unit60 compares the input ID and password with the information stored inTable 1 to determine if the input ID and password matches with theinformation in the table for that particular website.

If the input ID and password are correct, the control unit 60 reads theID and password for the other websites and inputs the read ID andpassword into each corresponding website. Thus, the user can entermultiple websites by only entering a single log in command.

In addition, if the table does not have an ID and password for aparticular website, the control unit 60 can display a warning message tothe user via the display unit 30 or can automatically enter the input IDand password into the window that does not have the ID and password inthe table.

Hence, when the user inputs a correct ID and password into one of themultiple windows, the other appropriate ID and password can beautomatically input to the rest of the windows to enhance the user'sconvenience and facilitation.

FIG. 7 is similar to FIG. 6, but includes the selection boxes 130A,130B, 130C and 130D (similar to FIG. 5). Thus, the user can selectivelydetermine what windows are to simultaneously receive the input command.

Further, the information in table 1 may be stored in an external memory(e.g., a USB memory), rather than being stored in the memory unit 40. Inthis instance, when the external memory is loaded in the externalinterface unit 20, the control unit 60 can read the information storedin the external memory and apply the stored information (e.g., logininformation for particular websites) automatically to the multiplewindows that are configured to operate with each other. Thus, the userdoes not need to input the command into any window, but rather thisinformation is automatically input to the correct windows by the controlunit 60.

FOURTH EMBODIMENT

In the first to third embodiments of the present invention, anindividual toolbar is separately provided to each window. However, inthe fourth embodiment of the present invention, a universal toolbar isdisplayed. FIGS. 8-10 illustrate these features. FIG. 1 will also bereferred to in this description.

As shown in FIG. 8, the control unit 60 displays at least two Internetbrowser windows on the screen of the display unit 30 (S81). For example,FIGS. 9 and 10 illustrate the three windows 100A, 100B and 100C beingactivated and displayed and the window 100D being displayed asminimized. FIGS. 9 and 10 also illustrate the control unit 60 displayinga universal toolbar 200 on the screen of the display unit 30.

As shown, the universal toolbar 200 is provided to collectively controlall of the windows. Further, FIGS. 9 and 10 illustrate a bar type toolbar being displayed at the top portions of the multiple windows, but anytype of toolbar that is capable of collectively controlling all of themultiple windows can also be used.

Then, as shown in FIG. 8, the control unit 60 determines the user hasinput a particular command via the universal toolbar 200 (S82). Then,the control unit 60 applies the input command to the three windows 100A,100B and 100C (S83).

For instance, in FIG. 9, the user can input the ‘search’ command into akeyword input box 210 of the universal toolbar 200. Then, the input‘search’ command is collectively applied to the three windows 100A, 100Band 100C. The search results of each window are then displayed in thecorresponding windows.

Note that FIG. 10 is similar to FIG. 9, except that FIG. 10 illustrateseach window including a selection box 130A, 130B, 130C and 130D enablingthe user to select specific windows to be controlled via the universaltoolbar 200. This is similar to the features shown in FIGS. 5 and 7, andthus a detailed description thereof is omitted.

FIFTH EMBODIMENT

The fifth embodiment describes in more detail the ‘log-in’ command inputmethod being applied to the universal toolbar. FIGS. 11 and 12 includefeatures related to this embodiment. FIG. 1 will also be referred to inthis description.

In this embodiment, an ID and password of a terminal user for eachInternet site are stored in the memory unit 40 of the terminal 1 asshown in the example Table 2 below.

TABLE 2 Representative Password freewill Internet Site ID Password yahoochulsoo ch1234 google chulsoo1 ch12345 altavista kimchulsoo kim1234 MSNkimchulsoo kim1234

Further, the IDs and passwords for the respective Internet sites can beequal to or different from each other. As shown in FIG. 11, the controlunit 60 controls the display unit 30 to display at least two Internetbrowser windows. In particular, FIG. 11 illustrates three windows 100A,100B and 100C being activated and displayed and the window 100D beingdisplayed as a minimized window.

Further, the universal toolbar 200 is also displayed on the screen ofthe display unit 30. As shown in FIGS. 11 and 12, the universal toolbar200 also includes the input box 220 that the user can use to input the‘log-in’ command.

For example, the user may input a representative password previously setin the terminal. Then, the control unit 60 determines whether therepresentative password is correct with reference to the informationshown in table 2 that is stored in the memory unit 40. If the inputpassword is correct, the control unit 60 applies the correctcorresponding ID and password to the three windows 100A, 100B and 100C(and window 100D).

Thus, if the user enters the password “freewill” in the input box 220,the appropriate ID and password for each particular website would beread from table 2 and input into each corresponding window.

Thus, when the user inputs the correct representative password into theinput box 220, the correct ID and password can be automatically input toall of the windows. Hence, the user's convenience and facilitation isenhanced. FIG. 12 is similar to FIG. 11, except the windows include theselection boxes 130A, 130B, 130C and 130D. This is similar to theselection boxes shown in the other embodiments, and thus a detaileddescription thereof is omitted.

SIXTH EMBODIMENT

In the fourth and fifth embodiments of the present invention, theuniversal toolbar is displayed as a default. Thus, it is possible tocontrol all of the windows using the single universal toolbar. In thesixth embodiment of the present invention, the user can selectivelyactivate a universal toolbar, if needed, and then control the windowsvia the activated universal toolbar. This embodiment will now beexplained with reference to FIGS. 13 to 15. FIG. 1 will also be referredto in this description.

In more detail, as shown in the flowchart of FIG. 13, the control unit60 controls the display unit 40 to display at least two windows (S131).Similar to the other embodiments and as shown in FIGS. 14 and 15, thecontrol unit 60 controls the display unit 40 to display the threewindows 100A, 100B and 100C as being activated and displayed and theother window 100D as being displayed as a minimized window.

Thus, with reference to FIG. 13, the control unit 60 determines if theuser has requested a universal tool bar be displayed (S132). If the userrequests the universal toolbar the displayed (Yes in S312), the controlunit 60 controls the display unit 40 to display a universal tool bar.For example, FIG. 15 illustrates a universal toolbar 200 beingdisplayed. Then, when the user enters a command into the universaltoolbar 200 (S133), the control unit 160 applies the command to all ofthe windows 110A, 110B, 100C and 100D (or the windows that the user hasdesignated as multi-cooperation windows) (S134). Otherwise (No in S132),control unit 60 controls each window separately (S135). FIG. 14illustrates each window including its own toolbar.

Therefore, in this embodiment, when the user wants to control thewindows simultaneously, the user can enter a specific command via theinput unit 50 so the control unit 60 displays the universal toolbar 200shown in FIG. 15. Further, the displayed universal toolbar 200 ispreferably displayed as an OSD (on screen display) feature on thedisplay unit 30.

In addition, the user may request the universal toolbar 200 be displayedby pressing or manipulating a separate function key (not shown in thedrawings) provided with the input unit 50. Also, if the display unit 30includes a touch screen, the touch screen may include a soft key thatthe user can touch to have the universal toolbar 200 be displayed.

SEVENTH EMBODIMENT

FIGS. 16-19 illustrate features of the seventh embodiment. FIG. 1 willalso be referred to in this description. In the seventh embodiment, theuser can select any displayed window (or multiple displayed windows) andhave the selected displayed windows displayed being equal in size.

In more detail, and as shown in FIG. 16, the control unit 60 controlsthe display unit 30 to display at least two windows (S161). This step issimilar to embodiments discussed above. Then, the user selects one ormore of the windows that he or she wants to be equally displayed (S162).The control unit 60 then displays the selected windows as being equal insize (S163).

For example, FIG. 17 illustrates the three windows 100A, 100B and 100Cbeing activated and displayed and the window 100D being displayed as aminimized window. Also, as mentioned above in some of the otherembodiments, the four windows 100A, 100B, 100C and 100D respectivelyinclude the selection boxes 130A, 130B, 130C and 130D enabling the userto select specific windows that he or she wants to interoperate witheach other.

Therefore, as shown in FIG. 17, the user has selected the three windows100A, 100B and 100C. Thus, in this instance, the control unit 60controls the display unit 30 to display the windows 100A, 100B and 100Cas being equal in size, and the unselected window 100D as beingdisplayed as a minimized window.

Likewise, FIG. 18 illustrates the user only selecting the windows 100Aand 100B. Thus, the control unit 60 controls the display unit 30 todisplay the windows 100A and 100B as being equal in size, and the othertwo windows 100C and 100D as being minimized. FIG. 19 illustrates allwindows 100A-100D being selected, and therefore being displayed as equalin size.

Therefore, according to this embodiment, the windows that are selectedvia the selection boxes are displayed equal in size, whereas the windowsthat are not selected are minimized.

Further, when the display unit 30 includes a touch screen, the user cansimply touch the selection boxes to designate a particular window tointeroperate with other selected windows. The user can also simply toucha soft key in the toolbar to have that command input to all selectedwindows. The user can also perform any other input operations on theterminal by touching the appropriate portions of the touch screen.

Accordingly, the present invention provides several advantages.

First of all, the user can apply one command to a plurality of displayedwindows. Thus, the user does not have to input the command to eachwindow. Secondly, the appropriate login information (e.g., ID andpassword) are stored in the memory, and the user can enter logininformation into one window, and have the appropriate login informationautomatically entered into other windows.

Thirdly, the user can easily select windows that he or she wantsdisplayed equally in the screen, without having to manually resize eachwindow.

It will be apparent to those skilled in the art that variousmodifications and variations can be made in the present inventionwithout departing from the spirit or scope of the inventions. Thus, itis intended that the present invention covers the modifications andvariations of this invention provided they come within the scope of theappended claims and their equivalents.
